public class AssetDatabaseExamples : MonoBehaviour { [MenuItem("AssetDatabase/Contains Example")] static void ContainsExample() { //Material is created in memory and the Asset Database does not know about it var material = new Material(Shader.Find("Specular")); Debug.Log(AssetDatabase.Contains(material)); //Output will be false //Material is then saved to disk as an asset and therefore Asset Database knows that it exists AssetDatabase.CreateAsset(material, "Assets/Materials/MyMaterial.mat"); Debug.Log(AssetDatabase.Contains(material)); //Output will be true } }
